Answer:
- <em><u>B) Bill's wagon is moving 4 times faster than Tom's. </u></em>
<u />
Explanation:
The motion of the wagons is determined by the net force that acts upon them, according to Newton's second law of motion:
- Force = mass × acceleration ⇒ acceleration = Force / mass
From your data, you can fill this table to compare the accelerations:
Bill's wagon Tom's wagon
mass (lb) 10 20
force 2F F
acceleration 2F/10 F/20
Find the ratio between both accelarations:
- Bill's wagon acceleration / Tom's wagon acceleration
- (2F/10) / (F/20) = (2 × 20 / 10 ) = 4
Meaning that the acceleration of Bill's wagon is 4 times the acceleration of Tom's wagon.
Assuming, that both wagons start from rest, you can obtain the speeds from the kinematic equation for uniformly accelerated motion:
- Speed = acceleration × time, V = a × t.
Call the acceleration of Tom's wagon X, then the acceleration of Bill's wagon will be 4X.
So, depending on the time, using V = a × t, the speeds will vary:
t (s) 1 2 3 4
Speed Tom's wagon X 2X 3X 4X
Speed Bill's wagon 4X 8X 12X 16X
Concluding that Bill's wagon is moving 4 times faster than Tom's (option B).
The bond that exist between two oxygen atoms is
called a double covalent bond. This bond involves the sharing of four electrons
to obtain a more stable structure. This type of bond is much stronger than the
single covalent bond. They are much harder to break.
